AIM To evaluate the anti-angiogenesis action of Bevacizumab on corneal neovascularization(CNV) in rats induced by alkali burns.·METHODS: 20 Health Wistar rats, aging from 6 to 8 weeks and weighting from 170g to 190g from 170g to 190g were prepared for CNV animal models. Both corneas of each animal in experimental were cauterized with alkali, then all rats were randomly divided into four groups (each group have 5 rats and 10 corneas), the both corneas of each rats were received subconjunctival Bevacizumab in different dosage (group 2, 0.5rag; group 3, 1.0mg; group 4, 2.0mg)and the group 1 received carrier solution. The occurrence and development ofCNVwereobservedbyslit-lamp microscope, and length and area of CNV were calculated. All rats were followeded up 16 days after alkali burns. The 40 corneas were taken for histopathological examination. Vascular endothelial growth factor (VEGF) were detected in all rat corneas by immunohistochemistry method. ·RESULTS: In the bevacizumabotreated eyes, the vascular area was lower than in the control eyes. The treated group was statistical differences compared with the control group; when vascular area were compared between the treated groups, no statistical differences were observed. The histopathological findings showed that the inflammation cells and the neovascularity in each treated group were significantly fewer than that in the control group. The expression of VEGF markedly increased in CNV control group compared with bevacizumab-injected group. ·CONCLUSION: Subconjunctival application of a certain concentrations Bevacizumab could inhibit angiogenesis in rats corneas induced by alkali burns.
